ARXC.REL Settings and Use
Relay outputs of ARXC.REL can be configured for different behaviour (Type) and these types
can be combined together.
There are three cathegories of ARXC
Types
:
•
BCD-N
•
1-of-N
•
TOGGLE 1-4
Both
BCD-N
and
1-of-N
consist of a
group
of the first N relays (where N = 2, 3 or 4), where
changing state of relays obeys certain rules; rest of the relays in given ARXC are
free
to be
set/cleared/toggled individually. Both
BCD-N
and
1-of-N
can also optionally represent azimuths;
in that case they can be used as an
Antenna
in Menu→Heading, and subsequently be
controlled using the same methods (local, remote) that are used to control the physical rotator.
In
TOGGLE 1-4
type, all 4 relays are controlled
free
ly.
In
BCD-N
, state of relays within the group represents a binary
number
, relay 1 representing the
least-significant bit, relay N the most-significant bit in that number. Presets targeting
BCD-N
group can set the group to a particular
number
, or can increment or decrement the
number
corresponding to the
BCD-N
group. However, individual relays can still be controlled freely in
the
ARXC Control
window, as well as in Menu→System→ARXCx.
In
1-of-N
,
there is always exactly one relay switched on. This rule is enforced even when
controlling relays in the
ARXC Control
window and in Menu→System→ARXCx. Individual
relays can be assigned to Presets, however, when this Preset is clicked, this relay of the group
will be switched on and all other relays of the group will be switched off. Presets "moving" the
active relay forward and backward within the group, circularly, are available, too.
When one of the
Types
is selected, the menu window displays multiple items, depending on the
particular
Type
selected.
In default configuration, all 4 ARXC are set as "NOT
CONNECTED", and ARCO behaves as in older
versions without ARXC, namely in Menu→Heading
and in Presets setup.
As the first step of setting up ARXC, in
Menu→System→ARXCx for the given ARXC, is to
select
Type.
When changing from one
Type
to a different one,
several related configuration parameters are reset to
default e.g. individual ARXC relays and group names; if
this ARXC's group was selected as
Antenna
, this
selection is reverted to default antenna (i.e.
corresponding to the physical rotator with given offset and
other attributes, as it was in older versions); and all
Presets
targeting this ARXC will be changed to plain AZI
presets. To avoid inadvertent loss of these parameters,
changing ARXC
Type
is subject to confirmation.
